Bus Protection
GE provides enhanced reliability through advanced protection for a wide range of bus protection applications. Our highly skilled technology teams understand bus bar principles and protection techniques, and use them to design, manufacture and support bus protection solutions that can be applied to a vast array of applications.
High magnitude fault currents require high speed operation of the bus bar protection to limit damage. However, this high speed clearing must be balanced against the need for security. Tripping incorrectly for an external fault may cause large outages and jeopardize power system stability. Learn more in our bus principles and protection guide.

Multilin B30
The B30, a member of the UR family, provides busbar protection for up to 16 feeders with 6 differential zones. Communication between bay and central units is done using Process Bus (IEC 61850-9-2LE) or standard (IEC 61869) protocols. It offers a large color LCD display. It can also be used for centralized protection for MV substations requiring busbar, breaker fail and feeder phase/neutral/ground overcurrent and under/overvoltage protection.

MiCOM P741/2/3 Agile
Part of the MiCOM P40 Agile family of relays, consisting of the Agile P741 central unit and P742 and P743 peripheral units, the P74x Agile is engineered to provide a traditional distributed architecture for busbar protection with CT saturation detection and dynamic topology processing algorithms. It can accommodate up to 8 zones (plus a check zone) and up to 28 terminals.

MiCOM P747 Agile
The P747 Agile relay, a member of the MiCOM P40 Agile family, provides complete protection up to extra high voltage busbar configurations. It can accommodate up to 4 zones (plus check zone) and protect up to 18 feeders. The P747 Is particularly useful in double busbar with double bus coupler applications due to its high number of I/Os.

MiCOM P746 Agile
The P746 Agile, a member of the MiCOM P40 Agile family, provides an easy to engineer solution for smaller size MV and HV busbar configurations with up to 2 zones (plus a check zone) and up to 6 feeders (1 box) or 18 feeders (3 boxes, 1 per phase). It can also be used with process bus in 1 box applications.

MiCOM P145 Agile
The MiCOM P145 numerical relay provides fast and reliable high impedance busbar differential protection. The P145 provides voltage and current based buswire supervision with 10 function keys, 18 programmable LEDs and 16I/16O for busbar protection scheme logic, control and indications.

MiCOM P14NB Agile
The MiCOM P14NB numerical relay provides fast and reliable high impedance busbar differential protection in a compact case. The P14NB provides current based buswire supervision with 8I/8O and 4 programmable LEDs for busbar protection scheme logic, control and indications.
